I must recommend this. Because of system re-installation, I formatized the backup of contact (iTools backup, database files, .db ending）on computer away. I downloaded this software and another one starting with the name an “M”. The “M” software could only recovered very few data. This one recovered more than 60,000 data entries… I was afraid how I can recover so much. In the end, I can find them easily according to the paths. As I found the phone numbers, I came back here to give it a good review! I must recommend this.
